[Effect of electroacupuncture intervention on learning-memory ability and injured hippocampal neurons in depression rats].

Objective: To observe the effect of electroacupuncture (EA) stimulation of "Baihui" (GV 20)-"Yintang" (EX-HN 3) on changes of learning-memory ability and hippocampal neuron structure in chronic stress-stimulation induced depression rats.

Methods: Forty-eight SD rats were randomly divided into normal, model, EA and medication (Fluoxetine) groups, with 12 rats in each group. The depression model was established by chronic unpredictable mild stress stimulation (swimming in 4 degrees C water, fasting, water deprivation, reversed day and night, etc).

[Effects of electroacupuncture of unilateral and bilateral "zusanli" (ST 36) on serum TNF-alpha, IL-1 and IL-4 levels in rats with chronic inflammatory pain].

Objective: To observe the effect of electroacupuncture (EA) on serum tumor necrosis factor-alpha (TNF-alpha), IL-1 and IL-4 levels in rats with chronic inflammatory pain, so as to investigate its underlying mechanism in relieving pain. Methods Forty-eight SD rats were randomized into control, model, EA-unilateral ST 36, and EA-bilateral ST 36 groups, with 12 rats in each. Chronic inflammatory pain model was established by intradermal injection of Freund's complete adjuvant (0.
